The Photon 30-pin interface
control drawing shows the pin numbers reversed for the interface
connector J1 (SAMTEC TFML-115-02-S-D-P), in comparison with SAMTEC&#8217;s
drawing for TFML-115-02-S-D-P. Why?

This question applies to the legacy Photon camera models. The
Photon product line and its accessories have been discontinued. The
information here is provided for historical reference.

At the time the Photon interface connector was designed,
SAMTEC was just introducing this part, and a pin numbering scheme was
not available. Unfortunately, when SAMTEC released their pin numbering
scheme, it differed from the one we had established. FLIR elected to
follow its own numbering scheme, already released in our documentation.
FLIR`s ICD correctly calls out pin function and pin location/ID.

Using SAMTEC`s drawing as a reference for the 30-pin connector
pinout will result in a failure of the Photon`s power conditioning
board.

This answer applies to all Photon versions: 640; 320; 160;
120; and 80.
